The major purpose of the proposed investigation is to examine the effects of a comprehensive, school-based, community-linked intervention on physical activity and physical fitness in middle school girls. Factors that mediate the effect of the intervention will be identified, and the intervention's impact on tobacco use, alcohol use, and depressive symptomatology will be observed. A collaborative, multi-center investigation will be conducted. At each of five field centers, six middle school catchment areas will be pair-matched and randomly assigned to intervention and control groups. In the intervention catchment areas a multi-component intervention, based on an ecological model and Social Cognitive Theory, will be implemented. The school physical education curriculum will be modified to emphasize in-class participation in moderate to vigorous physical activity and mastery of behavioral skills related to physical activity. Relationships will be established between the school and at least two community organizations that will provide after- school and summer physical activity programs for girls at the school site. in addition, after-school, weekend, and summer physical activity programs for girls will be expanded in community settings. Modifications will be made in several components of the school health program to link girls to the expanded physical activity program opportunities. Girls will be exposed to the intervention during their 7th and 8th grade years. Baseline measures of physical activity, physical fitness, other health characteristics and psychosocial/environmental factors related to physical activity will be administered during the spring of the 6th grade year, and this measurement battery will be re-administered during the 7th, 8th and 9th grade years. To determine intervention effects, statistical analyses of the physical activity and fitness data will be performed using mixed- model analysis of variance, with catchrnent area (nested within treatment) taken as the unit of analysis. It is hypothesized that the intervention will significantly reduce the usual rates of decline in physical activity and fitness seen in girls between the 6th and 8th grades. This study will uniquely and markedly expand our knowledge of promotion, determinants, and health benefits of physical activity in middle school girls.

本研究的主要目的是研究一项全面的、以学校为基础的、与社区相关的干预措施对中学女生身体活动和身体健康的影响。将确定干预效果的中介因素，并观察干预对烟草使用、酒精使用和抑郁症状的影响。将进行多中心合作调查。在五个实地中心的每个中心，六个中学集水区将被配对并随机分配到干预组和对照组。在干预集水区，将实施基于生态模型和社会认知理论的多组分干预。学校体育课程将被修改，以强调在课堂上参与适度到剧烈的体育活动和掌握与体育活动相关的行为技能。学校将与至少两个社区组织建立关系，这些组织将在学校现场为女孩提供课后和夏季体育活动项目。此外，将在社区环境中扩大为女孩提供的课外、周末和夏季体育活动项目。将对学校保健方案的若干组成部分进行修改，以便将女孩与扩大的体育活动方案机会联系起来。女孩们将在七年级和八年级接受干预。身体活动、身体健康、其他健康特征和与身体活动有关的社会心理/环境因素的基线测量将在六年级的春季进行，该测量组将在七年级、八年级和九年级期间重新进行。为了确定干预效果，将使用混合模型方差分析对体力活动和健身数据进行统计分析，以集水区（治疗内嵌套）为分析单位。据推测，干预将显著降低六年级至八年级女孩身体活动和健康下降的通常比率。这项研究将独特而显著地扩展我们对中学女生体育活动的促进、决定因素和健康益处的认识。
